LMX2572EVM: Using linux with the EVM

Saied,

The USB2ANY has its own DLL for exposing the communication API, and although I am not 100% sure about this, I believe it references Windows USB libraries and thus isn't portable (this is something we're working on for linux release). However, the LMX2572 has a header on the board for SPI communication from the USB2ANY, and it's just normal SPI. You could substitute any kind of SPI controller that supports 24-bit SPI, from FTDI to Raspberry Pi Pico. There are plenty of options.

Theoretically you could also reuse a lot of the LMX2572_PLL.py file as well:

• Comment out imports or inject your own fake imports to eliminate conflicts with .NET-specific code (recommend aliasing UpdateStatusBar as print function)
• Parse the LMX2572.ini file bits section to get register positions, lengths, offsets, etc.
• Create a class that exposes .iValue (integer), .dValue (float), and .sValue (string) properties, and potentially links to registers
  • Register-backed classes would trigger register writes as a side effect of updating their .iValue property
  • Could add something like a SetValue(x) function which emulates GUI interaction by assigning x to the appropriate property for its type and calling the control's associated _Update() function
